Comprehensive water regulation strategies in Taiwan were introduced, which is to begin with watershed protection, and then integratedly allocate the watershed, river, sewers and detention facility, and in the meantime lower the river flood level, combining the maintenance of the environment and ecology according to the basin flood hydrograph. Some engineering examples about the experiences of Taiwan river and wetlands regulation such as Taipei Dagouxi ecological detention pond, Hsintienxi Sunshine Sports Park, Taipei Guandu Nature Park Artificial Wetland (trough away style), Dahanxi River Bank Artificial Wetland (trough in style) were introduced. Those examples show that only by imitating the nature can the protection of ecological resources be promoted so as to realize the ultimate goal of sustainable development.
